摘要： In a magnetic resonance imaging apparatus and method, radio frequency signals are radiated into an examination subject and/or received from the examination subject by an array of radio frequency coils that completely encircles the examination subject, and that is located at a distance from the examination subject out of contact with the examination subject.

摘要： A patient positioning couch includes an illumination apparatus having at least one light source that is arranged in the patient positioning couch. The patient positioning couch is capable of being placed in an examination area of a medical device. Through the arrangement of the at least one light source of the illumination apparatus of the patient positioning couch, it is always ensured that the illumination does not lose its location relative to a patient or another object positioned on the patient positioning couch, even if the position of the patient positioning couch changes, e.g. if the patient positioning couch is moved into or out of the examination area. At the same time an especially space-saving illumination of the examination area can thus be achieved.

摘要： A magnetic resonance system for generation of magnetic resonance exposures of an examination subject in a patient positioning region has an antenna structure with a number of antenna elements arranged in the patient positioning region. Feed lines respectively supply the antenna elements with radio-frequency signals for emission of a radio-frequency field in the patient positioning region and/or to accept radio-frequency signals acquired by the antenna elements. The magnetic resonance system also has a radio-frequency shielding that shields an external region outside of the patient positioning region from radio-frequency signals radiated in the patient positioning region. This radio-frequency shielding has a number of feedthroughs through which the feed lines are respectively directed from the external region over a short distance to the antenna elements.

摘要： Longitudinal conductors (5) are led along intermediate spaces (9) between detector blocks (3); they lie entirely and centrally within these spaces. The wire cross section (5a) is round, of diameter 4 mm or more. The wires are spaced by 5-10 times their diameter, from the high frequency screen which separates the high frequency coil assembly and the positron emission tomography (PET) detector assembly (2). Using a birdcage high frequency coil, the end rings connecting the conductors (5) are arranged axially before and after the detector assembly.

摘要： A coil arrangement for a magnetic resonance system has a resonator that is followed by a modulator with which a magnetic resonance signal of the resonator is modulated onto a carrier frequency. An infeed element follows the modulator with which that magnetic resonance signal modulated onto the carrier frequency is supplied into a single transmission cable. In a corresponding reception circuit, an analog-to-digital converter is preceded by a demodulator with which the magnetic resonance signal is demodulated.

摘要： A generator of time-variable magnetic fields generator for a magnetic resonance apparatus has a primary gradient coil unit for generating of a gradient magnetic field in an examination region of the magnetic resonance apparatus. The primary gradient coil unit, for accommodating at least one gradient coil conductor, has a central region, an outer region and at least one connecting region connecting the two regions. The outer region surrounds the central region. At least one intervening space is disposed between the central region and the outer region. The intervening space is free of the gradient coil conductors of the primary gradient coil unit and a radio frequency antenna element is disposed therein. Such a generator enables an effective gradient field and RF field generation in a compact design combining a gradient coil and a radio-frequency antenna.
